Hi,
total of 11 coins (quarters + nickles = 11)
how many {{{highlight_green(x)}}} of the coins are nickles
Number of Quarters {{{highlight_green(11-x)}}}
CENTS makes sense
 25(11-x) + 5x = 155¢
  25•11 - 25x +5x = 155
  25•11 - 155 = 20x
       120 = 20x
         6 = x, the number of Nickels.  The number of Quarters is 5.   {{{11-6}}}

 5•25 + 6•5  = 155¢   0r $1.55
